REVERSIBLE wmoow SFECIFIOATION forming part of Letters Patent No. 627,164, dated June 20, 1899.

Application filed October 1, 1898. Serial No. 692,422. (No model.)

To all whom it ntcty concern:

Be it known that 1, WILLIAM T. WATER- STRAAT,a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and'useful Improvement in Reversible Windows, of which the following is a specification.

My invention relates more particularly to the class of reversible windows in which the sash is pivotally supported at its side stiles between slidingstiles confined in grooves in the window-frame to adapt the sash to be swung through a vertical plane to render its outer side accessible by presenting it to the interior of the apartment containing the window for convenience in cleaning, glazing, and painting it, and the like.

One of my objects is to provide for supporting the sash, to render it reversible, an improved construction of pivot device whereby it shall not protrude undesirably beyond the inner surface of the window and whereby more especially it shall afford thorough closure to the space in the plane it occupies between the side stile of the sash and the adjacent sliding stile, thus to exclude draft and prevent the light shining through said space. My further object is to provide for the reversible sash an automatic lock against accidental turning of the sash on its pivots.

Referring to the accompanying drawings, Figure l is a view in elevation of the inner side of a window having its lower sash equipped with my improvements; Fig. 2, an enlarged section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3, a similar section taken at the line 3 on Fig.

1 and viewed in the direction of the arrow;

Fig. 4, a similar section taken at the line 4 on Fig. 1 and viewed in the direction of the arrow; Fig. 5, an enlarged section taken at the line 5 on Fig. 3, viewed in the direction of the arrow and showing one of the pivotplates in side elevation; Fig. 6, an enlarged section taken at the line 6 on Fig. 3, viewed in the direction of the arrow and showing the other pivot-plate in side elevation; Fig. 7, a perspective View of the upper portion of a sliding stile surmounted by the catchportion of the automatic lock; Fig. 8, a similar view of a portion of the top sash-rail surmounted by a spring-latch of the automatic look for engaging with the catch Fig. 9, a perspective View of a sliding stile, and Fig. 10 a similar view of a sash-stile.

A is a window frame of any suitable general construction.

B is the lower sash, and B'the upper sash Only the lower sash is shown in the drawings as equipped with my improvements, though they are also applicable to the upper sash. Moreover, it may be here stated that my improved pivot device hereinafter described may be used with advantage on reversible windows, in which the sash is pivoted at its upper and lower ends to swing on a vertical axis. 7

In the vertical grooves 'r 1, provided in the opposite sides of the frame A, are confined, respectively, the sliding stiles C-C, each. provided with an offset extending throughout the length of its exposed side, forming a longitudinal shoulder 19, facing the inner side of the window-frame. From a point about midway between the ends of each sliding stile, abut ting against the shoulder 9, there extends to the lower end thereof a strip 1), thicker than the shoulder 19, to protrude beyond it a longitudinal shoulder 0, facing toward the outer side of the window-frame. Near the transverse center of each sliding stile C there is formed in its exposed side to extend backward or outward from its face a recess it, projecting into the shoulder 19 and of a form adapting it to receive a pivot-plate D, hereinafter described. I

In the side which opposes the exposed side or face of a sliding stile'of each stile C of the window-sash there is provided, extending, like the oifset on a sliding stile, from the inner surface of the stile to or beyond its longitudinal center, an offset forming a shoulder 10' of the The preferred form of each of the pivot-' plates D and D is that shown, involving flat sides having screw-holes, a straight front or inner edge provided with a flange m, straight 5 upper and lower edges, as shown at tin Figs.

5 and 6, and bowed or arc-shaped back edges, as shown at i. plates, on the faces thereof which oppose each other, are provided bosses l, the boss on one of the plates having a pivot-hole and that on the other plate carrying rigidly the pivot-pin D to enter the pivot-hole, in which it is riveted or otherwise fastened against withdrawal, but in a manner to permit the plates to turn one upon the other. About the outer bowed edge 75 of the pivot-plate D there is provided a laterallyextending curved flange i for a purpose hereinafter described.

When the sash B is in place in its normal upright position,with the pivot-plates in their recesses n n and connected near their inner edges bythe pivot-pin D the shoulders 0' on the sash-stiles abut outward or backward against and form weather-excluding rabbetjointsflvith the upper parts of the shoulders 19 on the sliding stiles, and the lower parts of these shoulders (below the pivotplate re- I ces'ses) abut in a forward or inward direction I against and form weather-excluding rabbetjoints, with the shoulders 0 on the sliding? The flan gesm onthe pivot-plates meet at their opposing edges, and at their opposite outer edges they respectively overlap to a? slight extent the faces of the sliding stiles and sash-stiles, and the bowed flange t on; each plate D conforms to and fits in the cor- .r'espondingly-shaped back of the portion of the corresponding sliding-stile recess n,which extends in the shoulder p,which back it overstiles.

laps, thereby closing the back of the space between cooperating pivot-plates and excluding draft and light between them.

the sash B a latch-finger 'i, pivoted between its ends to protrude at oneend into the path of the catch and controlled by a spring 1" to give it a tendency to engage with the catch. The spring-latch and catch thus form members of the automatic lock, the latch being normally behind the catch to abut against it, and thus prevent the sash'from being turned on its pivots, and being releasable by turning the latch on its pivot above the catch. The top of the catch is beveled, as shown at to present an inclined plane to the latch when brought against it by righting the sash and permit the latch to clear the back 70' and spring into engagement with the catch.

Near the front edges of thei To turn the sash B, the latches '1; are depressed -to release them from the catches k,

' when the sash may be swung upon its pivots,

and the pivoting of the plates D and D near their front edges enables the sash to be turned about completely with great convenience. In returning the sash to its normal upright position the latches slide over the inclined backs of the catches, and on clearing them spring into locking engagement with the catches to secure the sash against being accidentally turned.

What I claim as new, and desire to secure by Letters Patent, is

1. In a reversible window, the combination with the sliding stiles confined in grooves in the window-frame, and the window-sash, of recesses in the faces of the slidingstiles, pivot plates secured in said recesses, pivot-plates secured to the sash-stiles and having flanges ontheir back edges overlapping the slidingstile recesses, and pivot-pins connecting the sash and sliding-stile plates near their front edges, substantially as described.
